I worked in a company that used elastic search as main db.
It worked, company made alot of money from that project. It was a wrong decision but helped us complete the project very fast. We needed search capability and a db. ES did it both.
Problems that we faced by using elastic search:
High load, high Ram usage : db goes down, more ram needed. Luckily we had ES experts in infra team, helped us alot.(ecommerce company)
To Write and read after, you need to refresh the index or wait a refresh.
More inserts, more index refreshes. Which ES is not designed for, inserts become slow. You need to find a way to insert in bulk.
Api starts, cannot find es alias because of connection issue, creates a new alias(our code did that when it cant find alias, bad idea). Oops whole data on alias is gone.
Most important thing to use ES as main db is to use "keyword" type for every field that you don't text search.
No transaction: if second insert fails you need to delete first insert by hand. Makes code look ugly.
Advantages: you can search, every field is indexed, super fast reads. Fast development. Easy to learn. We never faced data loss, even if db crashed.
I just watched Tiangong space station with my bare eyes. Beautiful.
Looking forward to watch 14 starlink satellites tomorrow.
Thank you so much for your website.
There are tons of abondened places like this in Turkey and no one cares about them. They are used as barns these days.
Turkish government probably doesn't even know most of these places but treasure hunters loves them.
If you are interested with this stuff check this youtube channels.
This Turkish guy is a treasure hunter which is illegal. There are many treasure hunter youtubers in Turkey but this guy is the best because he is not faking it.
I enjoy it alot, highly recommended.
No English subtitles but you can understand what's going on.
OverTheWire wargames. I played first 10 levels, it's kinda fun, kinda frustrating but it made me read manuals of 'grep' and 'find' commands on bash. So it made me a better programmer for sure.

I love that game too!
Such a great game, that little game even has a final boss!
I sent miniclip a mail in 2012 asking for how to start programming and developing games and they replied! i still have that email in my inbox. At that time i was in highschool too but didn't start programming or anything related until university lol.
My first full time job as a junior dev was to maintain a legacy GWT project which makes tons of $ every year.Setting up the development environment took 1 week. For some odd reason we couldn't build the project module by module. Build was taking at least 2 mins with the bare minimum module count. I quickly become depressed. Waiting the builds and half way into build an error pops-up and you start again. This was 4 months ago, i literally became a deppressed junior dev who hates his job in 1 month. I started applying for job after a month and quit that job after 2 months.
